Definitions
- said reservoir or other elements of the flow circuit comprises at least one thermocouple po ⁇ sitioned at a probing point in said reservoir or said other elements, i.e. in said flow circuit.
- Said at least one ther ⁇ mocouple provides a signal to a control system, indicating that the temperature of the fuel and/or the pipework has reached a required level for liquid fuel starting. Therefore a control system could be provided to evaluate and/or to process said signal generated by said thermo sen ⁇ sor .
- a valve posi ⁇ tioned in the flow circuit, particularly at the inlet end of the reservoir or flow circuit, could be switched to direct the liquid fuel of the main fuel feed either (1) (directly) into the burners, both for normal operation and in a heating phase, or (2) towards the reservoir, in a starting phase.
- a pressure of the un- heated/cold fuel of the main supply then "drives" the heated fuel out of the reservoir into the burners.
- thermo sensor for example a thermocouple, indi- cates when the temperature of the liquid fuel to be heated in the reservoir is high enough for the gas turbine starting.
- the gas turbine is a Dry Low Emission gas turbine, that means the gas turbine is operating with a Dry Low Emission combustion. While supplying heated liquid fuel, particularly heated pres ⁇ surized liquid fuel, only for starting - during operation the flame of the combustion system will provide enough tempera- ture as well as more/higher pressure is available during op ⁇ eration - the rate of heating does not need to be high. Fur ⁇ ther to that - while supplying heated liquid fuel from a res ⁇ ervoir in which a predetermined amount of liquid fuel is heated - instead of heating a continuous flow of liquid fuel flowing upstream to the burners - the rate of heating does not need to be high.
- the rate of heating does not need to be high, the temperature of the heating means and/or the sizes of the heating means themselves do not need to be high/large which reduce the risk of coking/overheating of liquid fuel by the heating means.
- Small heaters - preferably depending on a size of the gas turbine - could be used by the invention. Further advantages as well as advantageous features of the invention appear from the following description.
- thermocouple 40 is arranged in the recirculating circuit 10, i.e. the thermocouple 40 is - as it can be seen in Fig ⁇ ures 2 and 3 - located in the pipe 21.
- the thermocouple 40 is generating signals - according to a temperature of the liquid fuel in the reservoir 20, i.e. circulating in the recirculating circuit 10.
- the signals are transmitted to a control sys ⁇ tem for controlling the temperature of the liquid fuel, i.e. a temperature in the recirculating circuit 10, as well as the operational modes of the recirculating circuit 10.
- the rate of heating does not need to be high, the temperature of the heaters 24 themselves does not need to be high. Also the continuous flow of liquid fuel around the re ⁇ circulation circuit 10 means that the liquid fuel is not in contact with the heaters 24 for an extended period of time. Both these factors reduce the risk of coking/overheating of liquid fuel by the heaters 24.
